Our main assumption here is that the magnetic structure of the graphene layer in contact with magnetic material (with possible further restrictions as only certain magnetic planes, such as FM Fe(111) plane in AFM BiFeO\(_3\)  [1]}, [2]} could be efficient) repeats this magnetic material, or, in other words, that the magnetic proximity effect is (i) complete and (ii) does not cause back-action and does not modify the magnetic structure of the proximity material due to the presence of graphene. Existing experimental studies [3]} are consistent with these two assumptions, however, more research is needed to understand their limitations and the role of back-action. We furthermore disregarded the influence of dipole-dipole interactions on proximity-induced magnetism. We know that in 2D vdW magnets the situation can be even more complicated. For example, FePS\(_3\)  is a layered antiferromagnet with zigzag ordering (see e.g. Ref. [4]}), and for emergence of the zigzag order second- and third-nearest-neighbor exchange interactions are essential. It would be interesting to expand our research to include other types of interactions, relevant to a broader class of vdW materials.
